Heaven and Demon

High school teacher, Aoki is reluctant to go to the infirmary. Because he does not like the doctor there, Mr. Tengoku for no reason. But one day, he is forced to pay a visit to talk about a student who often skips class there. At the first contact, Tengoku easily sees through Aoki's nature of disguising an exemplary teacher, and smiles mysteriously. Tengoku tells him that he has been watching Aoki ever since he is assigned to this school. While discussing about the student, Tengoku points out the naivety of Aoki, and then gives him a kiss all of sudden. In his embarrassment, Aoki is unable to refuse at that moment. Later on, he remembers his childhood memories and starts to see his true self. What awaits for the timid teacher, Aoki? In the end, is he in heaven or hell? (Source: Takeshobo)
